證券市場主要功能之一,在於形成證券之公平價格,投資人可基於充足而正確的資訊,依證券價格之主觀體認,透過證券交易市場之供需關係,並經由市場經濟體制自由運作,以競價方式形成證券之買賣價格。然而,原應透過市場供需法則自然形成的證券價格,若有人透過操縱市場行為,以不實的交易行為,或散布不實的資訊,製造證券供需及價格變動之假象,則將發生誤導投資人,進而扭曲證券交易的價格與數量,破壞自由市場機能,減損市場籌集資本及資源有效配置功能等危害。因此,目前許多國家對於市場操縱行為咸明文禁止,而我國證券交易法承襲美國與日本立法例,在證券交易法第155條對於市場操縱行為同樣明文禁止。 有關我國證券交易法第155條第1項第3款「相對委託」,係市場操縱行為態樣之一,亦為經濟刑法所規範之對象,惟本款於主觀構成要件及客觀構成要件並不明確,有諸多疑義尚待釐清。因此,本文試圖先從市場操縱行為之概念、立法沿革及態樣進行理解,再從學理與實務上探討本款之構成要件及牽涉之相關問題,並輔以美、日立法例進行比較分析,期使本款能合於經濟刑法之規範目的下,俾利實務工作者能正確的認事用法,並作為日後立法或修法上的參考。
